This service we offer allows customers to bring in test articles and
perform various tests using the test equipment in our test laboratories.
In addition, we can discover and solve the underlying problem that is
hard to predict and provide test solution to improve test quality and get
an accurate result.

Although the conventional environmental simulation test is performed to shorten a designed validation test, lower the failure rate
of products, extend the service life of products and decrease the claims after the sale, the HALT and HASS apply the excessive
stress to a product to check its operational limit, destructive limit to verify the design.
Large-scale Vibration TestLarge-scale Vibration Test
■ Enriched large vibration testing system (fully equipped
with the maximum exciting force 180kN/100kN scale)
corresponding to assembling item, large product and
heavy specimen
■ Additional large triaxial vibration testing system
corresponding to the latest railway rolling stock
standard and seismic simulation
Our technical center received the accreditation on ISO/IEC 17025 "General requirements for the competence
of testing and calibration laboratories" and can issue the test data with accreditation marks listed. according
to UM. IEC/ISO 17025 also take the requirements in ISO/IEC Guide 25 in its technical requirements based on
the requirements in ISO 9001:2000. In addition, it requires the environmental condition necessary to estimate
uncertainty, validity confirmation, etc. Accreditation of testing laboratories according to this standard assesses
the conformity of technical competence as well as the operation and effectiveness of the quality management
system within the laboratory. Based on accumulated knowledge for over 40 years and accreditation, EMIC's
technical center gives a customer a reliable test result.

In performing the vibration test, the technical design of the fixture
for mounting a test article is essential.
The key role of the fixture is to fix a specimen and transmit vibration, in
particular transmitting vibration is most important.
The fixture becomes inherently deformed depending on the test condition
or vibration mode.
Depending on the vibration mode the fixture may not transmit vibration to
a specimen, therefore, the intended vibration test may not be performed.
The vibration mode shows distinctive changes depending on the differ-
ence in size and mass of a specimen and test conditions.
